If you've not got anything else to plant give them a go. I have grown potatoes on the east side of the house which is shaded by flats next door first off then the house after midday. You're not likely to get the yield that you would with a spring-planted crop but any potato is better than no potato! Trust this helps.

If I planted seed potatoes now (Feb 17) is there any chance I'd get a crop before winter sets in?

Potatoes need about 3 months to harvest from planting for 'new' potatoes. That is about a month after flowering. If you can get 3 months before frosts give it a go or plant them in a frost-protected area. New potatoes are delicious but won't store like Old potatoes which are harvested after the tops die off. Trust this helps.

Is January too late to plant potatoes and if not which variety should I consider? Thanks for your advice

See Otago Daily Times Friday 20 January, "plant early maturing potatoes now for harvest at Easter."

You can plant a late crop of potatoes in January as long as you have sprouted seed ready. One thing to be wary of is the Psyllid bug as it is active as the weather warms up. There are mesh products available that you drape over the crop and that keeps the bugs off.

Two questions: Will Dutch Creams grow in Southern Qld and are Dutch Cream organic seed potatoes available in New Zealand?

I have grown some potatoes in flexi-bins - the light cheaper ones, 30 and 40 litre sizes. Drainage holes I melted into the sides of the containers with a hot pipe (neat holes) about 50mm or 2" up from the bottom. The holes being higher, allows a pool of water to remain in the pot and excess to drain out. Try a little potting mix about half full and top up the shoots with straw etc. Works well and containers are reasonably easy to move if required.

Hi, We have planted some potatoes and they are almost ready to harvest. I'm not really sure of the variety as my husband planted some potatoes, not from seed. It looks like there are some seed pods forming whee the flowers are. Can we use these for our next crop? If so, what do er have to do?

It depends -- not all potatoes are suitable for towering (layering). Additionally, I have found that the potato plant SPENDS A LOT OF ENERGY GROWING UP, UP, UP, as you cover its leaves with soil (leaves have specialized cells designed to collect light - and why you would want to cover them with soil is beyond me this is not really a good move -- leaves are not roots). My recommendation is: if you have a DEEP PLANTER bag starting at about six inches from the bottom -- in sort of a pattern that looks like the 5 on a die (dice) -- make about 3-4 inch round holes -- and make them on the sides that receive light keeping the holes about 10 inches apart (6 inches away from the bottom and 10 inches away from the top of the bag). Fill the bag with a good soil/compost/manure mix of some kind -- starting from the bottom -- when you are level with a hole, place a seed potato there, level or slight below the bottom lip of the hole, and about 3 inches from the side of the bag (so there is soil between the potato and the hole) -- continue up until the bag is full -- the top layer of potatoes can be planted as usual. Yes, the soil will come out of the holes ... not to worry -- just be sure that the soil covers the topmost holes by at least 6-8inches. That is - each potato planted in the bag should have access to a WINDOW (air and light) OR those planted on the top layer (like a usual planting) should be down about 9 inches or so. The Key to this planting is ALL potatoes need to be able to put leaves somewhere -- they will follow the air and light to find that spot -- all potatoes need water -- so you will be watering from the top of the bag only (like a potted plant) -- but you water DEEPLY, since the water needs to make it to the very bottom potato plants -- so maybe you water every 5 days or so... depends on the soil, temperature, amount of light , amount of wind/air (which whisks moisture away), Additionally, ensure there is drainage at the bottom of the bag .... maybe a two inch hole directly at ground level. It might be better to use a crate of some kind.... rather than a bag...anyhow this set up will work with any kind of potato plant without consideration as to whether or not it can handle towering. Hope this helps. Conversion of inches to cm : 1 inch = 2.5cm
